Then the computer generates some codes which may simply go over our head, but For example, if you want to know the direction of the wind, AfterĪll the data is collected and read, this layer transforms into a form in which Layer- This is the last layer of the current version of NMEA 2000. It is only necessary if one network is not enough to support all the This layer is not necessary for all NMEAĢ000. Like a boss or the head in a company, Network Layer looksĪfter everything and interacts with other companies, i.e. Now that we have learned about the regular employee (Data Link Layer), the manager (Network Management), its time to learn about the boss that is
It claims and assigns address on the network, identifiesĭevices that are connected with the network and initializes network at That’s where the network managementĬomes into play. Manager, then things will go haphazardly. Management- Data Link Layer connects different nodes, but if there is no Is important to connect all the small network nodes to the main network.
NMEA is connected to lots of different devices, so a data link layer This means that the layerĭenotes the relationship of physical devices with the network.Īs the name says, this layer carries or transfers data from one network node toĪnother. This layer defines the electrical and mechanical aspects of the physical linkīetween network connections and references the characteristics of the devicesĪnd network interfaces to be used in NMEA 2000. NMEA 2000 network is made up of lots of components, but theyĬan be classified into five major components:
